I was happily modifying an XSD and it ran into this.

Hi Pascal, any chance you still have the schema and perhaps remember what you were doing at the time you got the NPE?
Comment 2 Keith Chong CLA 2010-11-03 01:12:28 EDT 
Hi Galileo, please have a look at this.
Comment 3 Galileo Perez CLA 2010-11-04 11:46:17 EDT 
Created attachment 182389 [details]
Added a try catch block to avoid the NPE while setting text

While the attribute isReference object is null and the code tries to setText it throws an NPE, this exception was avoided adding a try catch block
